We look at the division of 74951211 by 15 
Our goal is to divide 74951211 by 15.

On to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 15

On to step 2:
The number 15 fits into 74 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 74 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 15

Going ahead to step 3:
The number 15 fits into 149 9 times, leaving a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 14 after subtracting 135 from 149.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 15

Going ahead to step 4:
145 divided by 15 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 499.0
Subtracting 135 from 145 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 15

On to step 5:
The number 15 fits into 101 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 4996.0
The remainder is 11 after subtracting 90 from 101.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 15

On to step 6:
15 can be fit into 112 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 49967.0
If we take 105 away from 112, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 15

On to step 7:
71 divided by 15 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 499674.0
Subtract 60 from 71 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 15

Going ahead to step 8:
15 goes into 111 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 4996747.0
Deduct 105 from 111 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
15 goes into 60 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4996747.4
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4996747.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4996747.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4996747.4 with a remaining 0.0.
